WS-SECURITY XMLSDIG Canonicalization.DigestValue.Signature RSA-SHA256

I'm looking for someone who already has a great deal of experience in this field, not someone who's going to start figuring out how to do it. I want someone who already knows how to do WS-security-XMLsdig-DigestValue-certsRSA authentication by analysing the documentation on 2 pages and using the header/body given as an example.

Required : ASAP availability, experienced in this field. PHP/SOAP/XMLSDIG/DigestValue/CERT.RSA/Canonicalization EXC-C14N/SAML ASSERTION REQUEST IN BODY SOAP XML
